A influência da internet no marketing internacional e relacional das empresas

O presente relatório tem por base o estágio curricular realizado no âmbito do mestrado em Marketing Relacional, lecionado na Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Leiria. O estágio, com uma duração de 1096 horas, decorreu na empresa Smartidiom, Lda., cuja atividade principal é a prestação de serviços linguísticos. A Smartidiom, Lda. opera no mercado internacional desde a sua fundação e pode ser definida como uma empresa born-global. No entanto, o reforço da internacionalização afigura-se indispensável para uma empresa que pretende expandir a atividade e se confronta com um mercado nacional exíguo, como é o mercado português, que atravessa um período de modesto dinamismo económico. O reforço da internacionalização é também uma ambição natural numa economia global, baseada no conhecimento. As tarefas realizadas contribuíram para este objetivo de intensificação da internacionalização e incluíram aspetos relacionados com o marketing internacional, como a elaboração do plano de marketing internacional da empresa e com o marketing relacional, como, o contacto com clientes através da rede social de âmbito profissional, o LinkedIn. Dado o âmbito do mestrado e as tarefas desempenhadas, era importante analisar o papel da internet no marketing internacional e na construção de estratégias relacionais com clientes estrangeiros. Com este intuito foi realizada uma revisão da literatura, que permitiu concluir que o uso da internet nas atividades de marketing internacional é particularmente importante para as pequenas empresas, dada a escassez de recursos disponíveis. As características internas das empresas, como o domínio das tecnologias da informação, condicionam o uso desta ferramenta. A literatura mostra que as empresas reconhecem a importância das redes sociais na construção dos relacionamentos com os clientes. No entanto, a utilização destas no contexto específico do marketing internacional carece de análise empírica.

“Comulgar con ruedas de molino”: el cierre del Fray Gerundio en 1840

Fundado en abril de 1837 por Modesto Lafuente, el Fray Gerundio fue el principal periódico satírico de su tiempo, así como uno de los más populares y vendidos. Su crítica permanente al poder le valió varias amonestaciones por parte de los distintos gobiernos, la última de las cuales acabó con su cierre en marzo de 1840 por desacato, una acusación que luego se comprobó contraria a la ley. El cierre lo hizo aún más popular y convirtió a Modesto Lafuente en una verdadera celebridad por su defensa de la libertad de imprenta.

Face description for perceptual user interfaces

[EN]We investigate mechanisms which can endow the computer with the ability of describing a human face by means of computer vision techniques. This is a necessary requirement in order to develop HCI approaches which make the user feel himself/herself perceived. This paper describes our experiences considering gender, race and the presence of moustache and glasses. This is accomplished comparing, on a set of 6000 facial images, two di erent face representation approaches: Principal Components Analysis (PCA) and Gabor lters. The results achieved using a Support Vector Machine (SVM) based classi er are promising and particularly better for the second representation approach.

Combining human perception and geometric restrictions for automatic pedestrian detection

[EN]Automatic detection systems do not perform as well as human observers, even on simple detection tasks. A potential solution to this problem is training vision systems on appropriate regions of interests (ROIs), in contrast to training on predefined and arbitrarily selected regions. Here we focus on detecting pedestrians in static scenes. Our aim is to answer the following question: Can automatic vision systems for pedestrian detection be improved by training them on perceptually-defined ROIs?

Una propuesta de instalación basada en Habilidades de Visión por Computador

An analysis of facial description in static images and video streams

[ES]This paper describes an analysis performed for facial description in static images and video streams. The still image context is first analyzed in order to decide the optimal classifier configuration for each problem: gender recognition, race classification, and glasses and moustache presence. These results are later applied to significant samples which are automatically extracted in real-time from video streams achieving promising results in the facial description of 70 individuals by means of gender, race and the presence of glasses and moustache.

Multiple face detection at different resolutions for perceptual user interfaces

[EN]This paper describes in detail a real-time multiple face detection system for video streams. The system adds to the good performance provided by a window shift approach, the combination of different cues available in video streams due to temporal coherence. The results achieved by this combined solution outperform the basic face detector obtaining a 98% success rate for around 27000 images, providing additionally eye detection and a relation between the successive detections in time by means of detection threads.

Real-time detection of faces in video streams

[EN]This paper describes a face detection system which goes beyond traditional approaches normally designed for still images. First the video stream context is considered to apply the detector, and therefore, the resulting system is designed taking into consideration a main feature available in a video stream, i.e. temporal coherence. The resulting system builds a feature based model for each detected face, and searches them using various model information in the next frame. The results achieved for video stream processing outperform Rowley-Kanade's and Viola-Jones' solutions providing eye and face data in a reduced time with a notable correct detection rate.

Hand pose detection for vision-based gesture interfaces

[EN]Vision-based applications designed for humanmachine interaction require fast and accurate hand detection. However, previous works on this field assume different constraints, like a limitation in the number of detected gestures, because hands are highly complex objects to locate. This paper presents an approach which changes the detection target without limiting the number of detected gestures. Using a cascade classifier we detect hands based on their wrists. With this approach, we introduce two main contributions: (1) a reliable segmentation, independently of the gesture being made and (2) a training phase faster than previous cascade classifier based methods. The paper includes experimental evaluations with different video streams that illustrate the efficiency and suitability for perceptual interfaces.

Who are you?

[EN]Most automatic recognition systems are focused on recognizing, given a single mug-shot of an individual, any new image of that individual. Most verification systems are designed to authenticate an identity provided by the user. However, the previous work rarely focus on the problem of detecting when a new individual, i.e., an unknown one, is present. The goal of the work presented in this paper deals with the possibility of providing the system with basic tools to detect when a new individual starts an interactive session, in order to allow the system to add or improve an identity model in the database. Experiments carried out with a set of 36 different individuals show promising results.

Identity and gender recognition using the ENCARA real-time face detector

[EN]This paper presents recognition results based on a PCA representation and classification with SVMs and temporal coherence.

Fast and robust face finding via local context

[EN]In visual surveillance face detection can be an important cue for initializing tracking algorithms. Recent work in psychophics hints at the importance of the local context of a face for robust detection, such as head contours and torso. This paper describes a detector that actively utilizes the idea of local context. The promise is to gain robustness that goes beyond the capabilities of traditional face detection making it particularly interesting for surveillance. The performance of the proposed detector in terms of accuracy and speed is evaluated on data sets from PETS 2000 and PETS 2003 and compared to the object-centered approach. Particular attention is paid to the role of available image resolution.
